Each number wheel is firmly connected with a toothed wheel 50. These toothed wheels 50 gear with toothed wheels 51 freely mounted on an intermediate shaft, with which toothed wheels 51 otherv toothed wheels 52 gear which are provided with pro jections 53 formed as number or figure printing types. With each number wheel there corresponds a type wheel52 by means of which figures or numbers corresponding to those visible beneath the apertures 2, 3, 4, of the casing may be printed on a paper band 54, which in order tobe printed is moved past the type wheels in a suitable on a shaft 55 (Figs. 1, 2 and 3 The first I group of chain wheels on the s aft 55 consists of the chain wheels 56, 57, 58, 59, the second group of the chain wheels 60 wheels68, 69, 70, 71, the fifth group of the chain wheels 72, 73, 74, 75. The chain wheel 56 drives the number wheel 10 by means of 'a' chain and chain wheel 31, the chain wheel chain wheel 35, the-chain wheel 64 drives the number wheel 12 by means 'ofthe chain wheel 35, the chain wheel 68 drives the num- 67 by means of. the

her wheel 13 by means' 'of the chain wheel 37 and the chain wheel 72 drives the number wheel 14 by means of the chain wheel 39. The chain wheel 57 drives by means of the chain wheel 21 the number wheel 5, the chain wheel 61- by means of the chain'wheel 23 the number wheel 6, thechain wheel 65 by means of the chain wheel 25 the number wheel 7, the chain wheel 69 by means of the chain wheel 27 the number wheel 8, the chain wheel 73 by means of the chain wheel 29, the number wheel 9.

The chain wheels 57, 61, 65, 69,73 are have toothed segments which are-in engagementwith the toothed wheels 74, 75, 76, 77, 78 and carry pointers or indicators 90,

. which, when the hand levers are turned on their axis move over scales which consist of the numerals O 'X and are placed on the 1 wallof the casing at one side of the apertures through which the hand levers pro ect. The shaft 79 is shown in Fig. 1 in dotted lines. The chain wheels 56, 58,60, 62, 64,-

i 66, 68, 70, 72,74, are freely'and displaceably mounted on the shaft 55. The wheels have annular grooves 91 in which *forks 92 engage, which are firmly connectedwith a rod 93, The rod may be moved to and fro longitudin'ally. The chain wheels 56-7 5 are rovided on one side with clutch teeth 94 y means of which the displaceable chain wheels of each group may be alternately coupled with the chain wheels of their group which are non-displaceably mounted on the shaft 55.

61 62, 63, the third group of the chain wheels 64, 65, 66, 67, the fourth group of the chain number wheel 11 by means of '59 d V 6h a shaft 96 (Fig.1) shifting drums 97,

The chain wheels 58 and 59 are coupled with one another by clutch teeth 94 which are held in engagement with one another by means of a spring 95. The clutch teeth are saw shaped so that the chain wheel 58 can move in one direction relatively to the chain, wheel 59 without carrying the ,chain wheel 59 withit. The chain Wheels 92, 63,

66, 67, 70, 71, 74 and are arranged in similar manner to the chain wheels 58 and provided with springs 95.

98, 99,100 are revolubly but not displaceably mou ted. Each shifting drum has rings of teeth 101. Opposite the rings of teeth 101 elbow levers 108, and 109 (Fig. 4) are pivotally arranged on av shaft 110. The two arms of each elbow lever are flexibly connected with oneanother at 111. The' a pawl 114 which is revolubly-mounted, at

115 and is pressed bymeans of a spring 116 mounted on the arm against the arm, so that the pawl can yield upward against the pressure of the ,spring 116, but must always carry the arm with it when downward pressure is exerted on it. The pawls 114 of the elbow levers project into the paths of the rings of teeth (Fig. 4). The shifting drumsare under the action of a helical spring 118, Fig. 1, one end of which is fixed on the hub of the respective shifting drum. and the otherend'on a rod firmly connected with the casing.

Chain wheels 120, 121, 122, 123, serve for winding the springs 118, of which wheels, 120 is firmly connected with the shifting drum 97, 121 with the drum 98, 122 with the 101 of the shifting drums drum 99 and 123 with the drum 100. The

chain wheel 120 is'operated from the chain wheel 58, the chain wheel 121 from the chain wheel 62, the chain wheel 122 from the chain wheel 66and the chain wheel-123 from the chain wheel 70. When these chain wheels are-operated the drums are rotated in the direction indicated by the arrow, and the springs 69 are simultaneously wound. The

chain wheel 74 operates a chain wheel 124 revolubly-mounted on the shaft 96, which wheel is under the influence of a helical-- other ends of the pawls.

spring loaded pawls 145;

move on straight guides 146 and are co-n-' arms in one direction'and retain the chain wheels120-124 and the wheels connected with them against the pressure of the helical springs. The toothed wheels 125 have thirty teeth, the ratchet wheels 126, on the other hand, have only 10. Three spring loaded pawls 131, 132, 133, (Figs. 1 and 3), which are pivo-tally mounted on a pin 134, engage with each ratchet wheel 126. The fron ends of the pawls are displaced relatively to one another through 1/30 of the periphery of the ratchet wheel. An arm 135 of a double-armed lever, which is pivotally mounted on the casing at 136, engages the The other arm 137 of the lever is in contact with a cam 138 which is mounted on a shaft 139. A firmly keyed toothed wheel 140 (Fig. 10) is mounted on this shaft, which wheel with a gear wheel 141-revolubly mounted on the casing is operated by means of a toothed wheel 143 firmly connected with the cash till handle 142. v 1

A slide piece 144 (Fig. 3) isdisplaceably mounted under each toothed wheel 125. These slide pieces have restrictedly pivotal, The carriages nected with levers 148, pivotally mounted on a shaft 147, by means of resilient bars which are formed in twoparts. One part 149 of each bar is formed as a sleeve and the other part 150 has a projection 150 Between the parts 149 and 150 a spring 151 is interpolated, which allows of a displacement of the parts 149 and 150 relatively to one another when the part 150 is held fast, which may be done by the toothed wheel 125 being prevented from rotating. The levers 148 carry rollers 152 which encounter cam disks having cams 153,154 and 155.

The cam disks are firmly arranged on the shaft 139. On the rotation of the cam disks the levels 148 have a reciprocating motion imparted to them. In the movement to the left the pawls 145 encounter a tooth of the wheels 125 and turn these wheels to the cxtent of one tooth interval, that is to say,

left they engage a tooth of the ratchet wheels and can turn these through 1/10 of the periphery. The slide pieces are connected with rackbars 158 with which toothed wheels 159 engage. These toothed Wheels 159 are firmly mounted on a shaft 160 which has a bevel wheel 161 firmly keyed thereon which gears with a bevel wheel 162. The bevel wheel 162 is mounted on a shaft 163 which is operated by a toothed pinion 164 by means of .a. rack bar 165 which is firmly connected with the rod 93, (Fig. 1). One end of the rod 93 has a handle 166, the other end is arranged opposite a beveled, annular projection 167 of a toothed wheel 168 standing in engagement with the ear wheel 141. The coin ejecting slides or crawers 169, (Figs. 4 and 5), several of which may be provided one below the other, have apertures 170, each of which can receive a coin. The apertures 170 are formed at one side with slot. like extensions 171. In these slots 171 a pin 172 firmly connected with the casing engages, which pin serves. as a stop for the coin contained in the openings 170 and holds in the positions of repose, by means of the coin, the respective slide, the openings 170.1ying concentrically to the coin piling tubes 173 arranged over the ejecting slides 169. Each coin ejector is connected with a rod 174. The rods- 174 have annular contractions 175 and 176. The rods 174 are passed through apertures 177 of four displaceably mounted bars 178, which may be moved to and fro independently of one another, as will be hereinafter described. Yokes 179, so-ca'lled riders, are mounted 011 each of the bars 178, a rider beingmounted on the respective bar over each rod. The upper transwrse wall 180 of each rider is out out laterally. In these recesses or cut out parts projections 181 on the bars 178,

engage, so that the riders must always move vertically. Each rider is seated beneath a pin 112, so that these pins depress the riders whemthey are themselves depressed by the lower arm of .the corresponding elbow lever. Each rider is' slotted at its lower end. The slOt has two superimposed parts, the upper one of which is narrower than the lower, .(Fig. 8). The upper part 182 fits into the annular recess 175 of the bar, the lower part 183 of the slot has such a clear width that the full section of the bar can pass through this slotted part. In the position of the bars 174 shown in Fig. 4 the riders may be so far lowered that the narrow slotted part 182 passes into the constriction 175, whereby the bars 174.are coupled with the riders 179 and the bars 178.

In the position shown in Fig. 4 theriders 179 rest on elbow pieces 185 mounted so as to be capable ofrislng and falling, in a stationary"plate 184, the horizontal arms of with a pin 188 which has an annular recess tapered part 176 of the'rod to freely pass through when the elbow piece is raised, as shown in Figs. 4 and 7.

Each rod 174E has a ring 191. Against this ring a spring 192, which acts on a ring 193 movable on the rod, bears the said ring contacting with the surface of the rider. The spring 192 causes a displacement of the rod 174 to the left (see Fig. 1) when the ejector slide 169 connected with the rod contains no C0111.

The bars 17 8 are connected by means of a rod 194 with plates 195 whichare coupled with rods 196 which are displaceably mounted in straight guides 197. In the drawings only one bar 178, one plate 195 and one rod 196 are shown, as the representation of the other bars 178, plates 195and rods 196 would only mean a repetition of the arrangement. A draw bar 198 engages with the rod 196 and is flexibly connected with an elbow lever 200 pivotally mounted at 199.- The elbow lever 200 has a roller 201 which travels on the periphery of .a cam disk 202. The cam disk is firmly mounted on the shaft 139 and has a cam which on the rotation of the shaft moves the rod 196 together with the plate 195 and the bar 178 to the right, in order to pushforward the rods 171 when these are coupled withthe bar 17 8 by means of the riders 179.

Four plates 203 are displaceably mounted in fixed guides in front of the free ends of the rods 174. In the drawings only one plate 203 is shown as the others are formed and work in a similar way. On the displacement of the plate 203 to the right it encounters the rods 17-1 and thereby moves-the -slide 169 somewhat to the right. The plates 203 serve for shaking the rods 17% and the coin ejectors 169, in order to insure the corrcct position of the coin in the apertures 170. of the ejecting slides. Each plate 203 is connected with a rod 201 the end of which has a At the front end each of roller 205', which travels on the periphery of a cam disk provided with several cams 206.

The bars 178 also carry plates 207 which are provided with recesses 208. In these recesses movable slide pieces 209, so-callcd grippers, are arranged which have pins 210 which pass thnough apertures. in the plate 207 and are guided in these apertures. The

grippers are acted on by springs f211 which i tend to move the grippers always to the left and to press them againstthe'pins 188;

the grippers hasja.

slot 212, (Fig. 6). Constricted parts 213 of the pins 188 fit into these slots when the pins are depressed by means of the rlde-rs 179. The pins are then retained by the gripable way. For this object the rod 196 is coniieeted with a lever 214. The lever may be held in an approximately horizontal position by a stop mounted on the rod 196, but it may turn freely upward on its carrying axis. So long as the rod 196 is in the position of repose, the end 215 of the'leve'r 214 rests on a disk 217 provided with a cam 216, which disk is firmly mounted 011 a shaft 218. This shaft is operated by a toothed wheel 219 which is in engagement with the toothed wheel 1 10 of the shaft 139. In agiven position the cam 216 comes into engagement with the lever 214. When the shaft 218 is rotated to the left the cam 216 pushes the lever 21 1, the rod 196 and the bar 178 to the right, whereby the grippers 209 are re leased from the pins 188. Each rod 196 is connected with a similar arrangement, so that in all four disks 217 must be assumed to be mounted on the shaft 218.

A discharging slide or drawer 220 is mounted on the casing 1 beneath the ejecting slides of each coin pile and is movable by hand. The slide has an aperture 220 and a second aperture 22]. The aperture 220' is at least ofequal width to the apertures 170 of the ejector slide 169, in order that the coin may be removed from the coin piling tubes 173 when the aperture 220 passes under the aperture 170 by the drawer 220 being drawn forward. The displacement of the discharging slide or drawer 220 is limited by a pin 172. The second aperture 221 of the discharging slide and drawer 220 allows the coin pushed forward by means of the respective ejecting slide'169 to drop into the chamber 222 of the cash box and also serves to enable each discharging drawer to be seized bv hand and drawn to the right for the purpose of emptying the respective coin piling tubes 173.

Projections 223 of a yoke 224 which is displaceably mountedon the casing 1 are Located in front of the ends of the discharging slides or drawers 220. The yokcs rests on leaf springs 225 which tend to press the arms of the yokcs against a guide surface.

. The springs 225 allow the yokes to tilt downward and push them so far to the left. that the projections 223 snap into the apertures .221, whereby the yoke is coupled with all the discharging slides 220 and. by drawing forward the yoke 224 all the coin piling tubes are simultaneously emptied. The coin passes out of the chamber 222 into the receiver 226 outsidethe casing.

A rod 227 on which apawl 228 is pivotally mounted M229, is fixed on each rod 174, and on the displacementof the rod 174 to the left thepawl can slide up the back of the corresponding elbow lever 108,109,s0 that on the depression of the arm 108 by means of one of the-teeth 101, the shifting drum is lifted. Each pawl 228 engages in a recess 230 of a vertically movable plate 231 which is mounted in guide bars 232. This plate is pushed upward by the lifting of atleast one of the pawls 228. ln the lowered position tlie'plate 231 serves as a stop for. the elbow lever 10.8, 109, and thus prevents the move ment of this lever to the right. In a raised position it releases the elbow lever, so that this can rock to the right without. influencing the riders 179. The'cash till has four plates 231. Each plate has a yoke 233 overlapping a traverse 235 connected with levers 234, mounted in the casing. One lever 234 has an arm 236 (Fig. 3) which comes in contact with a cam 237 on a disk which is connected with the cash till handle 142. So long as the cash ti-ll handle is in a position of repose, the lever arm 236 is in contact with the cam and this presses the arm downward, so that the plates, 231 remain raised.

The arms 109 (Fig. 4) of the elbow lovers have projections 238 on which bars 239 restwhich are firmly connected with a shaft 240 which is mounted in the casing. An arm of.

a lever 241 (Fig.3) engages the bar 239, which lever is under the action of a spring 242. The upper end of the lever 241 has a tooth pawl 243 which is pivotally mounted at 244 and pressed by means of a spring 245 against a stop 246 on the lever, so that the pawl of the lever may be turned to one side against the pressure of the spring. The pawl 243 engages a disk 246 revolubly mounted on the casing wall 1, which disk has teeth 247, 248, 249. A handle 251 (F 1, 10 and 11) is fixed on theshaft 250 of the disk, which handle engages in a rectangularly shaped slot 252 of a sleeve 253 fixed on the casing. The shaft of the disk is revolubly and displaceably mounted in the sleeve and is acted on by a spring 254, which tends to axially displace the disk. The axial displacement of the disk takes place automatically when this disk has come thrice into engagement with theteeth of the disk by means of the lever 241 and the pawl 243 has successively moved the teeth 247249. The three progressive movements of the disk moves the handle 251 out of the radially directed part of the slot 252 into the axially directed part of the same, whereb the spring 254 is released and the sha t 250 amount received is at least one decimal larger than the amount to be paid. Axially displaceable sleeves 256 are arranged on a shaft 255 over the four ratchet wheels 126,

which sleeves have finger-like project-ions 257. placed relatively to one another, so that on the rotation of the sleeve 256 to the right, the lowermost projection 257 first depresses These projections are arranged disthe pawl 131, then the next projection the pawl 132 and finally the upper projection the pawl 133 in such a way that the pawls successively release the ratchet Wheels 126 and these each time runbackward under the influence of the helical springs '118 to the extent of 1/30 of the periphery. The sleeves 256 are connected with the ends of springs 258, the other ends of which springs are secured to a rod 259 (Fig. 1). The springs hold the sleeves 256 in the position of repose and are stretched on the'rotation of the sleeve for the purpose of lifting the pawls 131, 132 and 133. A spring 260 which bears on the one hand on the sleeve Wall and on the other hand on a clutch disk firmly connected with the shaft 255, is provided in each sleeve 256, while the teeth of the clutch disk may engage in suitably formed recesses in the sleeve 256. The spring 260 e011- stantly tends to release the sleeve 256 from engagement with the clutch disk 261. Four similarly shaped sleeves 256 and four simi larly shaped clutch disks are arranged on the shaft 255.

Each sleeve 256 has an annular groove 262 which may be brought into engagement with a lever 263 for throwing the apparatus into and out of action. The levers 263 are pivoted at 264., The arm of the lever which acts onthe sleeve is provided with an extension 265 (Fig. 3) formed with a hooked part which may be turned downward against the pressure of a leaf spring 266 mounted on the lever, and brought'into engagement with the annular groove of the sleeve. The other arm of the lever projects into the lowermost part of the path of each of the hand levers 80, 81, 82, 83, which corresponds to the figure X on the scale, andhas an inclined cam 267 which the respective hand lever pushes and thereby causes the movement for bringing into action the operating lever 263. In order that the levers 263 may come into engagement with the annular grooves of the sleeves 256, twoarmed levers 269, 270, 271, 272, (Fig. 1), are mounted on a shaft 259, which levers carry at one end rods 274, 275, 276, 277 and at the other end a pin 278 which encounters a disk 279. The disks are connected with the chain wheels and have a recess 280 (Fig. 3). The pins 278 enter the recesses so long as the chain wheels are in the zero position, while the hooked ends of the levers 263 are raised. If, however, the chain wheels are turned by means of the hand levers 80, 81, 82, 83 in order to adjust them to any suitable number beyond zero, the pins 278 are expelled from the recess 280 of the disks 279, the lever arms connected with them raised and the rods 274-277 depressed, which move the hooked ends of the levers 263 into the annular grooves of the sleeves 256, whereupon the sleeves 256, by turning the hand levers 80, 81, 82, 83, up to the number X of the scale, may be brought into engagement with the clutch disks 261.

A toothed wheel 281 '(Fig. 10) is mounted on the shaft 255, which wheelv is in engagement with a toothed segment 283 pivoted on the wall of the casing at 282. The toothed segment is connected with a lever arm 284. which may be moved by means of a key 285 (Figs. 10 and 12). The key has an enlarged part 286, a blade 287 and a cylindrical projection 288 and fits in a key hole 289 of a device resembling a lock, which has for its object to lock the cash till handle 142 and only allow of the cash till being operated by the possessor of a suitable key. In the lock plates 290, 291, 292, are arranged one above the other. The outer plate 290 contains the key hole 289 and a slot 293 connected therewith, the width of which'is equal to the diameterof the key shank, so that the edges of the plate engage over the enlarged part 286 of the key. The slot 293 and a slot 294 arranged in the plate 291 are circular in form in their parts lying nearest to the key hole, but are otherwise straight. The plate 292 forms a bottom on which the cylindrical projection 288 of the key can slide and has holes 295, 296, of different sizes, the clear widths of which correspond to the difierently sized cylindrical projections of the keys. The enlarged part of the key is guided in the slot 294 so long as the cylindrical projection of the key slides on the bottom. 292, without entering the hole 295. On the key being moved from the key hole to the hole 295 the enlarged part of the key carries the lever arm 284 with it until it slips oil the key and under tli eaction of a spring 297 returns to the inltlal position shown. By the lever 284 being carried along with the key the shaft 255 is turned, so that the finger-like projections on the sleeves 256 can engage the pawls 131', 132, 133. During the displacement of the key in'the slots 293 and 294 the plate 298 prevents the key being turned around on its axis. WVhen the key is inserted in the hole 295 the blade is beneath the plate 298 and can then be turned. In doing this it encounters a bar 300,.Which is displaceably mounted and is under the action of a spring 299, carries this bar and an arm 301 of an elbow lever with it until the key blade is beneath the aperture 302 of the plates 298, 290, 291, whereupon the key may be withdrawn.

an arm 310 of the elbow lever. The places at which the key blades act on the bar are so arranged thateach can only be reached by the respective key. r 7

The elbow lever has an arm 312 which is connected by rods 313,314, and an elbow lever 315 with a rack bar which gears with a toothed wheel 317 connected with a type wheel 316. The type wheel 316 carries the types 318 bearing the names of the salesmen who use the cash till, and is loosely mounted on a shaft 319. The rod 313 is connected The bar 300 is formed at I 303 as a rack bar which engages with a with a two-armed lever 320, the arm 321 of Y which projects beneath the edge of the slot 294 when the elbow lever arm 391 or the arm 310 connected therewith, is forced by a key out of the position of repose. The extent of the movement of the arms 301'and 310 is limited according to the size of the key-used and consequently the extent of the rotation of the type wheel 306 is regulated so that it may be seen by its adjustment what salesman has used the cash till. If the position of the type wheel be marked'on a.

paper band, the use of the cash tillmay be checked. By the elbow lever arms 301, 310,

being forced out of theii 2 position of repose,

the end of the lever arm 31 is moved within reach of the path of the enlarged part of the key and remains in this position until a key" is afresh pushed forward from the key hole into the operating position, whereby the lever arm 321. is forced back and the type wheel 316 moved back into the zero position, before the type wheel can be again adjusted. The number type wheels 52 (Fig. 3) are mounted on the shaft 319, and are operated by means of toothed wheels from the corresponding number indicating disks 15-19.

Number type wheels arearranged on shafts 322 and 323. Some .type wheels 52 gear by means of toothed wheels with the number wheels 10-14 and other type Wheels 52 by toothed wheels with the number wheels .5-9. The paper band 54 is drawn past the type wheels, and the printing .may

.be effected by means of suitable auxiliary mechanism.

The hubs of the chain wheels 9, 3, 67, 71, 75 have grooves 326 (Fig.1) with which the levers 327, for throwing into and out of action, engage, which levers are controlled by cam disks 328 firmly mounted on a shaft. 329. mounted on this shaft, which wheel has on one side an inclined projection 167 arranged opposite the right hand end of the rod 93 and serves for pushing the rod to the left when the end of the rod encounters the projection.

I 337, so that spurious coins which pass into this aperture fall through it into a receiving hopper 338. A bridge 339 is provided between the apertures 335 and 337 in the passage 333. The opening in said bridge is of the same width as the apertures 336 but is so low that the genuine coins encounter the bridge and in consequence of the pushing action of the slide 334 are conveyed along the inclined bridge to the aperture 336 which can receive the genuine coins. Coins which are too much worn therefore pass through the bridge aperture to the aperture 337 and from there into the re ceiver 338.

The genuine fcoins drop into apassage 339.

in front of the slide 340 and are conveyed by the latter to the piling tubes 173. Beneath the aperture 336 there is an aperture.

closing. member is retained by a pawl 343 which engages in a .slot in the casing 1.

' The slide 334 is connected with a lever 344 cam disk 352. .These cam disks are firmly The toothed wheel 168 is in the drawings.

mounted on shaft 353 which is operated by a chain 354 (Fig. 1) which is actuated.

by the cashtill handle 142. The cams are so arranged that amovement of the slides 334 and 340 can only take place when the-cash .till handle has moved past the shaft 250,

that-is to say the device provided on the cash till for testing whether the ejecting slide containssutficient coin, When coin is wanting in the ejecting slides a. signal, for instance a reddish 356,- (Fig. 4), appears behind apertures 355, which disk 1s c0nnected with arod 357 with which one or more rods 227 engage when their respective ejecting slides contain no coin, that is to say make an additional movement to the left.

The coin conveyed to the coin tubes 273 operates a. pawl 358 (Fig. 16); which is firmly mounted on a shaft359 and connected with a lever 360 which operates the ratchet or shifting pawl of the counting mechanism. The ratchet or shifting pawl and the counting mechanism are'not shown The action of'the cash till is as follows Assuming a purchaser has topay 15 marks and he tenders 20 marks, the salesmanmoves the number wheels tothe. amount to be paid: 15 marks, takes place by means of" the chain wheels 64 and 68 coupled with the levers. The salesman then pushesthe rod 93 to the right against the toothed wheel 168, whereby the chain wheels 64 and p 68 are uncoupled .from the hand levers,

'while the chain wheels 66 and 67 are couvers 270 and 271 respectively acting on the 'eam disk 279 and the corresponding lever 263 for throwing into and out of action is movedmto the annular grooves of the correspondmg sleeve and the sleeve 256 moved by the hand lever 82 coupled with the shaft 255. During the second movement of the hand levers 82 and 83 the amount 8 paidz20 marks, is adjusted by the chain wheels 65 and 79 and, as change or balance of the amount 15 marks, by the chain wheels 67 and 71, and the shifting drums99 are turned forward through 1/10 and the shifting drums 98 through 5/10. The salesman now unlocksthe cash till handle by means of a key and thus turns by means of the toothed segment 283 and the ':0othed wheel 281 the shaft 255. and the sleet e coupled with it. The pawls 131', 132, 133, of the ratchet wheel 126 of the shifting drum 99 are thereby successively lifted, so that this shifting drum can run back through 1/10 of its periphery taking with it by means of. the chain wheel 70 the chain wheel 71 c0upled with it and moving back the number wheel coupled with this chain wheel 71 throughl/lO in order that an amount of 5 marks may remain as change.

By means of the unlocked cash till, handle 142 and the shafts which are in engagement with it, are turned,flwhereby the projection 167 of the toothed wheel 168 first moves the rod 93 together with the disengaging levers 92 to the left in order that the shifting drums and the chain wheels mounted with them on the shaft may leave the indicating members uninfiuenced until their 'return into the position of repose. The testing of the pile of coins thentakes place by the turning of the cams" 153, 154, 155, the ejecting slide being simultaneously shaken. If there is no 5 mark piece in the corresponding ejecting slide, this slide and its rod 174 connected withthe pawl 228 are displaced backward by means of ts spring 192 into an inoperative position, in which a broad part of the said rod is beneath the corresponding rider 179. The said pawl 228 is hereby moved up the back of the correspondin elbow lever On turning the toot led wheel 125 and the shifting drum 98 the arm 108' is depressed by means of one of the teeth of the said wheel on the pin 112 locked by means of the rider 179 riding up the broad part of the rod 174, the arm 109 is turned upward, pushes the plate 231 upward by means of the pawl 228 and actuates the bars 239, the'lever 241, the .pawl 243 of which displaces the disk 246, to one tooth 247, the ratchet-pawl 132 is comin into the engagement with the ratchet-wieel 126 in order to stop the shifting drum 98 in a new position. In the new position of the'rshifting drum 98, two teethof the latter are in the operative position and are ready to actuate two corresponding slides 169, one for a 2 mark piece and the other for a 3 mark piece. These elbow levers deflect to teeth of the shifting drum five separate one mark pieces.

when the coins arewanting, whereupon the third adjustment of the shifting drum can take place by means of-the lastofj the cams 153, 154, 155, in order, for instance, to eject Should even these notbe present, the deflection of the elbow levers for the third time and also the throwing into action of the shaft 250 for the purpose of locking the handle 142 takes place. If the handle is arrested by the shaft 250 it is turned somewhat backward in orthe upper slot of the elbow lever.

der to push back for the purpose of uncoupling, the grippers, which are coupled, for instance, with the pins 188, and thereby to again press up into its original position the previously depressed rider 179 by means of normal position of the ejecting slide, the an-,

nular contraction 17 5 of the rod 174 connected with the said slide isbeneath the rider.

179. On turning the toothed wheel 125 and the shifting drum 98, one arm 108 being supported by the plate 231 is depressed by means of one of the teeth of the said drum on the pin 112, Which pushes down the rider 179 into the annular contraction 175, in or-- =der to couple the corresponding ejecting slide with the bar 178 which then by means of the cam disk 202 operated by the cash till handle 142 pushes forward the ejecting slide and ejects the coin; On the ejecting slide being pushed forward the corresponding gripper holds the angle piece 185 depressed, until the contraction 176 has passed through After the ejection of the coin theejecting slide is moved back into the initial position by the spring which acts u on it. Before the rotation of the cash till andle 142 is completed, the cam 138 of the shaft 139 presses down the lever arm 135 on the pawls 131-133, and releases them, so that the chain wheels 120-124 can return to their initial position under the action of the helical springs 118.

During the movement of the elbow levers 108 by the shifting drums, that is to say during the testing of the coin pile as to its contents 'and during the lowering of the riders, the coupling between the chain wheels '58 and 59, 62 and 63, 66 and 67, 70 and 71 and 74 and 75, is released in order that the number wheels indicating the change or balance may remain uninfiuenced. The uncoupling of these wheels takes place by means of the cam disk 328 and the lever 327 engaging there vith.
